<h4><a name = "tag_000_010_247">&nbsp;</a>NAME</h4><blockquote>
uname - get name of current system
</blockquote><h4><a name = "tag_000_010_248">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="sysutsname.h.html">sys/utsname.h</a>&gt;

</code>
</pre>
</blockquote><h4><a name = "tag_000_010_249">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>uname()</i>
function stores information identifying the current system in the
structure pointed to by
<i>name</i>.
<p>
The
<i>uname()</i>
function uses the
<i>utsname</i>
structure defined in
<i><a href="sysutsname.h.html">&lt;sys/utsname.h&gt;</a></i>.
<p>
The
<i>uname()</i>
function returns a string naming the current system in the character array
<i>sysname</i>.
Similarly,
<i>nodename</i>
contains the name that the system is known by on a communications
network.
The arrays
<i>release</i>
and
<i>version</i>
further identify the operating system.
The array
<i>machine</i>
contains a name that identifies the hardware that
the
system is running on.
<p>
The format of each member is implementation-dependent.
</blockquote><h4><a name = "tag_000_010_250">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion, a non-negative value is returned.
Otherwise, -1 is returned and
<i>errno</i>
is set to indicate the error.
</blockquote><h4><a name = "tag_000_010_251">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_000_010_252">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_010_253">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
The inclusion of the
<i>nodename</i>
member in this structure does not imply that it is sufficient information
for interfacing to communications networks.
</blockquote><h4><a name = "tag_000_010_254">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
